FreeRADIUS+VLANs

Hi, I found a few articles online about dynamically assigning VLAN IDs to users using RADIUS, this article was the most useful: http://searchsecurity.techtarget.com/general/0,295582,sid14_gci1169011,00.ht... I tried setting up something like this from that page using my mysql tables in FreeRADIUS: Tunnel-Type=VLAN (13) Tunnel-Medium-Type=802 Tunnel-Private-Group-ID=VLANID But it doesn't seem to be working. Has anyone had any experience in doing this? It could just be that my NAS isn't compatible but I'd like to know if anyone has had any success doing this and any advice you could give. Thanks, Darren Maden
